random_number_list

Creates a list of randomly drawn numbers from a larger list. Can be used to pick lottery numbers.

Installation

Run the following to install:

pip install random-number-list

Usage

from random_number_list import RandomNumberList

new_list = RandomNumberList.return_list(number, pick, put_back)

print(new_list)

print(RandomNumberList.verify_number(number))
print(RandomNumberList.verify_pick(number, pick))

Example

new_list = RandomNumberList.return_list(15, 5, False)

print(new_list)

returns:

[12, 9, 1, 8, 4]

Basis of operation

When the object is called, you pass the following variables:

number:

The number of items in the pool to be picked from.
example:
number = 5 will create a pool [1, 2, 3, 4, 5]

pick:

The number of items to be randomly drawn from the pool.
example:
pick = 2 will return a list of the randomly drawn items, say [4, 2]

put_back:

Whether an item is put back into the pool prior to the next draw.
Input as a boolean True or False, with a default of False.

error_text:

Optional Boolean variable with a default of False.
If True is passed, a simple explanatory error message is output.

Note:

digits after a decimal point are ignored.
5, 5.0, 5.2 & 5.9 all equate to 5

Methods

RandomNumberList.return_list(number, pick, put_back, error_text)

Used to create the list of randomly drawn numbers:

RandomNumberList.verify_number(number, error_text)

Validates that a number greater than or equal to one has been passed.

RandomNumberList.verify_pick(number, pick, error_text)

Validates that:
number: is greater than or equal to one
pick: is greater than or equal to one AND less than or equal to number

This package has been built as part of my learning Python so may contain coding that is not best practice. I am happy for more experienced Python users to feedback any areas that could be improved. Once I get to understand uploading packages to PyPI I will set up development dependencies.
